Cracking and slumping of the Halema‘uma‘u crater walls are clearly evident in this aerial view captured during HVO's overflight of Kīlauea's summit this morning. Steam plumes have been rising from within the crater, as well as from cracks adjacent to the crater.

Map as of 10:00 a.m. HST, June 9, 2018. The fissure 8 flow has created a lava delta approximately 200 acres in size, filling Kapoho Bay and shallow reefs along the nearby coastline.

Video of the lava ocean entry during today's late afternoon overflight of the lower East Rift Zone. The main steam plume marks location where the primary lava channel enters the ocean.

An aerial view of the Kapoho ocean entry, as of 6:30 a.m. HST today, shows the extent of the lava delta, now about 200 acres in size, that has formed over the past six days (lava first entered the ocean on the night of June 3).

Another aerial view showing prominent cracking around Halema‘uma‘u from the ongoing subsidence at Kīlauea's summit. The steaming cracks in the background have been observed for several days.

Map as of 12:00 p.m. (noon) HST, June 8, 2018. Given the dynamic nature of Kīlauea's lower East Rift Zone eruption, with changing vent locations, fissures starting and stopping, and varying rates of lava effusion, map details shown here are accurate as of the date/time noted. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

This thermal map shows the Fissure 8 lava flow along the coast, as of 12:30 pm on Friday, June 8. The flow from Fissure 8 remains active, with the flow front entering the ocean at Kapoho. The thick gas plume from the ocean entry obscured sections of the flow, producing several artifacts in the thermal map.

Dramatic changes at Halema‘uma‘u could be seen through gases rising from the crater during HVO's overflight of the summit this morning at 10 a.m. HST. The view here looks to the southwest, with the former overlook parking lot barely visible to the left of the gas plume.

HVO's early morning helicopter overflight of Kīlauea's lower East Rift Zone showed that lava continues to flow into the ocean in the vicinity of Kapoho Bay and Vacationland.

Outgassing from Halema‘uma‘u produced twin pillars that rose in the still morning air and merged into a towering cap above the summit of Kīlauea just after sunrise.

Around 3:00 a.m. HST today (June 8), lava fountains erupting from fissure 8 on Kīlauea Volcano's Lower East Rift Zone were reaching heights of 180–220 feet.

On June 6, at 4:07 p.m. HST, an explosion within Halema‘uma‘u sent an ash and gas plume to a height of about 10,000 feet above sea level. The explosion released energy equivalent to that of a magnitude-5.6 earthquake; a result of the explosion-related energy release was ground shaking felt throughout the summit area.

Lava entering the ocean in the vicinity of Kapoho Bay is forming a lava delta, as seen from the air during this morning's overflight at about 7:00 a.m. HST.

Fissure 8 lava fountain heights fluctuated between about 40 m (130 ft) and 70 m (230 ft) during this morning's overflight at about 6:30 a.m. HST.

Crack on Crater Rim Drive just east of the parking lot, with the National Park sign indicating "Halema‘uma‘u" at right. This crack shows 42 cm (16.5 in) of right lateral offset—as measured by fitting the center stripe on the road back together)—and was about 25 cm (10 in) wide.

Lava enters the ocean in the vicinity of Vacationland at 7 a.m. HST. The ocean entry produces a white plume called "laze," which drifts downwind. Laze is composed of steam, hydrochloric acid and tiny volcanic glass particles, which can irritate the lungs, eyes and skin.
